The several bridge laws referenced in § 114.01 Purpose, are intended to prevent any interference with navigable waters of the United States whether by bridges, dams, dikes or other obstructions to navigation except by express permission of the United States. The decision as to whether a bridge permit or a drawbridge operation regulation will be issued or promulgated must rest primarily upon the effect of the proposed action on navigation to assure that the action provides for the reasonable needs of navigation after full consideration of the effect of the proposed action on the human environment. The Coast Guard is not responsible for any other permits that the applicant may need from other federal, state, or local agencies and issuance of a bridge permit does not affect flood control projects or other governmental programs.

(a) If the final inspection shows a minor departure from the authorized plans which does not materially affect navigation, the permittee will be required to furnish a tracing showing the work as actually constructed but no further action will be taken by the Coast Guard.

(b) It is not the practice of the Coast Guard to issue letters certifying that completed work conforms to that which was authorized. That question is a matter of fact to be determined in case of controversy by the usual rules of court procedure.

§ 114.25Work constructed without prior authority.

The Commandant or District Commander will approve plans and issue permits authorizing bridges across navigable waters, in cases where the application therefor is submitted after the commencement or completion of the bridges subject to the following rules: Approval will be limited to those cases where the necessary primary authority, State or Federal as the case may be, validly existed, when the work was innocently constructed, and where the work will not unreasonably interfere with navigation. Upon issuance of the permit, applicant will be informed that the law contemplates prior approval and that in the future plans must be submitted in ample time for their consideration by the Commandant or District Commander before construction is begun.

Permits may be revoked by the issuing official for failure on the part of the permittee to comply with any of the conditions therein, or where the structures or other work constitute an unreasonable obstruction to navigation or to operations of the United States in the interest of navigation or flood control.

[CGD 82-006, 47 FR 36640, Aug. 23, 1982]§ 114.40Violations of law.

The Coast Guard has the authority and responsibility for enforcement of the applicable provisions of law for the protection and preservation of navigable waters. It is the policy of the Coast Guard to secure compliance with these provisions of law short of legal proceedings. As a general principle, no action is taken when the violation is minor, unintentional, or accidental and the party responsible corrects the violation. It is the policy of the Coast Guard to implement civil or criminal proceedings in all other circumstances. These proceedings are in subpart 1.07 of Part 1 of this chapter.

Extensions of time to commence or complete construction of a bridge or remove a bridge that has been replaced as an element of a permitted bridge project must be submitted to, and received by the District Commander at least 30 days before the existing permit expires to allow the permit to remain in effect until the final agency action is taken.

A District Commander's decision to deny a bridge permit application or an application for drawbridge operation regulations may be appealed to the Commandant, U.S. Coast Guard. The appeal must be submitted in writing to the Chief, Office of Bridge Administration, 2100 Second Street SW., Washington, DC 20593-0001, within 60 days of the District Commander's decision. The Commandant will take action on the appeal within 90 days of its receipt.

This part states the requirements for applying for a permit for construction of or modification to bridges crossing the navigable waters of the United States. It also sets forth the procedures by which the application is processed by the Coast Guard.

For bridges constructed by State or municipal agencies, the primary authority will be presumed without proof. If the law of the State requires a license for or approval of the bridge from a constituted State agency, a copy of such license or approval will be required and may be accepted as evidence of the primary authority. If there be no State regulation of bridges in navigable waters, the necessary primary authority may be that granted in the charter of a corporation, or the authority inherent in the ownership of the land on which the structure is placed. The applicant will in such cases be required to furnish an extract from the charter, or a statement of ownership. Especial care will be taken that Federal approval is not granted when there is doubt of the right of the builder to construct and utilize the bridge.

§ 115.10Limiting date in permits.

(a) Specific time limitations are inserted in all permits for the commencement of construction and completion thereof. Normally three years for start of construction and two additional years for completion may be allowed.

(b) Specific time limitations are inserted in all permits for the removal of bridges being replaced in whole or in part by the newly permitted bridges where removal thereof is required as a condition of the permit. Normally 90 days for removal after completion of the new bridge or opening to land transportation, whichever occurs first, may be allowed.

When compensatory works or the removal of temporary structures should be required of the permittee, or in other unusual cases when there is reason to anticipate that the permittee may fail to carry out parts of the work that are against his interest, an additional condition will be included in the permit requiring the permittee to furnish a bond insuring compliance with the permit requirements.

§ 115.20Transfer of permits.

Permits express merely the assent of the Federal Government so far as concerns the public rights of navigation. Although issued to a specific party, the assent is not limited to execution of the work by that party and may be availed of by the assignees or purchasers of the property affected, provided the terms of the instrument are strictly complied with.

§ 115.30Sufficiency of State authority for bridges.

An opinion of the attorney general of the State as to the sufficiency of State authority for the construction of a bridge is acceptable to the Coast Guard in doubtful cases.

§ 115.40Bridge repairs.

Repairs to a bridge which do not alter the clearances, type of structure, or any integral part of the substructure or superstructure or navigation conditions, but which consist only in the replacement of worn or obsolete parts, may, if the bridge is a legally approved structure, be made as routine maintenance without approval of the U.S. Coast Guard.

§ 115.50Application for bridge permits.

(a) Approval of plans. An application for authorization to construct a bridge across navigable waters of the United States must show the name and address of the applicant; the waterway and location of the bridge; citation to the act of Congress or the State legislature authorizing the bridge; be accompanied by a map of the location and plans of the bridge showing the features which affect navigation; and papers to establish the identity of the applicant.

(b) Prior authority necessary. Except as provided under paragraph (c) of this section, a bridge cannot lawfully be constructed across any navigable waterway of the United States until the location and plans have been approved by the Coast Guard.

(c) Prior authority not necessary. Coast Guard approval of the location and plans for construction or modification of a bridge or causeway is not required for any bridge or causeway over waters which are not subject to the ebb and flow of the tide and which are not used and are not susceptible to use in their natural condition or by reasonable improvement as a means to transport interstate or foreign commerce, whether or not such waters were used or were susceptible to use, at some previous time, to transport commerce (historic use). This provision does not apply to bridges which connect the United States with any foreign country.

(d) Form. The application for the approval of plans consists of a letter accompanied with maps and plans of the proposed structure.

(e) Signature. In case of signature by an agent or by an official of a corporation, a duly authenticated copy of the authority for the action must accompany the application.

(f) Identification. If the applicant is a corporation, it must furnish certified copies of the following papers, all properly authenticated: The charter or articles of incorporation; the minutes of organization; extract from minutes showing the names of the present officers of the corporation.

(1) Where State laws vest in State or county officers, such as boards of supervisors and county courts, the power to authorize the construction of bridges, they must furnish with their application certified extracts from their proceedings showing their action authorizing the proposed structure.

(g) Plans. Four sets of plans must be submitted with the application, on which the location of the work and the essential features covered by the application will be outlined in red. Each drawing must have a simple title, date and number, preferably in the lower righthand corner.

(h) Size of sheets. The drawings will be on letter size sheets. As few sheets will be used as necessary to show clearly what is proposed.

(i) Special instructions. (1) The scale will be shown graphically. The north and south line will be indicated by a meridian arrow. Soundings and elevations will be shown in feet and referred to the established Government datum plane at the locality.

(2) The direction of currents will be indicated by an arrow, and the strength of currents, both ebb and flow, or low water and high water, will be shown close to the proposed location of the bridge, and at both ends of the waterway shown on the map of location.

(3) The plans will show in figures the least clear height of the lowest part of the superstructure over navigation openings, with reference to the planes of mean high water and mean low water if the bridge is to cross tidal water. If the waters are nontidal, the least clear height will be shown with reference to the planes of extreme high water and mean low water. If records of river heights are available, the plane above which flood waters have not remained more than 2 percent of the time will be indicated. Reference will also be made to other datum planes if appropriate for the waterway in question.

(4) If harbor lines have been established at the site of the bridge, their position will be shown on the plans.

(j) Structural details. Only those should be shown which are needed to illustrate the effect of the proposed structure on navigation. If the bridge is to be equipped with a draw, the latter will be shown in two positions: closed and open.

(k) To whom application should be presented. The application and the papers and plans accompanying it should be submitted to the District Commander having jurisdiction over the area in which the bridge site is located.

The following procedures will be observed in the handling of applications for permits to construct, modify, or replace bridges over navigable waters.

(a) District Commander's review of application and plans. When an application is received, the District Commander verifies the authority for construction of the bridge, reviews, the application and plans for sufficiency, ascertains the views of local authorities and other interested parties, and ensures that the application complies with relevant environmental laws, regulations, and orders. If the application contains any defects that would prevent issuance of a permit (as for example, if the proposed bridge provided insufficient clearance), the applicant is notified that the permit cannot be granted and given reasons for this determination. The applicant may then request that the application be considered by the Commandant. If the applicant makes such a request, or if the application is not found defective, the District Commander notifies the public that it has been received and continues its processing. A copy of this notification will be sent to the state, interstate agency or the Environmental Protection Agency (EPA) responsible for acting on requests for water quality certification for the project. If the state, interstate agency, or the EPA fails to issue or deny the water quality certification within 30 days after receiving the copy of this notification, the requirements for a water quality certification are waived. If the appropriate agency notifies the District Commander that the applicant has not filed a request for water quality certification, or requests additional time to review an application, additional time will be granted.

(b) Public hearing. (1) Public hearings will be held when there are substantial issues concerning the effect that the proposed bridge will have on the reasonable needs of navigation.

(2) Notice of the public hearing will be published in the Federal Register. Notice of the hearing is also mailed to State, county, and municipal authorities and all other known interested parties. It is also posted at the post office nearest the site and public places in the vicinity.

(3) Hearings are public and conducted in an informal manner. A designated Coast Guard official presides. The submission of written statements is invited and encouraged. Anyone desiring to do so may speak. Statements, written or oral, are not under oath, and cross-examination is not permitted. No fixed order has been established for the presentation of evidence or argument although proponents are generally heard first, followed by opponents with full opportunity afforded for rebuttals.

(c) Report and recommendations. After the close of the comment period and any public hearings, a detailed statement of findings, conclusions, and recommendations based on all available information (including Coast Guard records and experience) is prepared. The following factors may be discussed in this report:

(1) Comparison of proposed bridge with existing bridges over the waterway; attitude of local authorities; summary of objections raised by the public, and District Commander's comments or responses; probable effect on navigation, present and prospective.

(2) Description of the navigation on the waterway past the site of the proposed bridge, the number and type of vessels, the number of vessel trips, and the principal method of handling traffic, whether in single vessels or in tows.

(3) Whether the District Commander approves, or recommends approval of the plans. If they are found objectionable, the reasons for this finding will be stated. If there are objectionable features in the plans which may be corrected, the applicant is given an opportunity to revise them. If approval is given or recommended, all conditions to which the permit should be subject will be stated.

(d) Action on permit application. (1) The District Commander may issue the permit if authorized under § 1.01-60(b) of this chapter; otherwise, a report with the application shall be submitted to the Commandant for final action.

(2) When an application is approved, the issuing official signs the permit and transmits it to the applicant.

(3) When an application is not approved, the applicant is notified and provided with reasons for the disapproval, and suggestions for modifications that would justify reconsideration, if appropriate.

(4) If an application is disapproved by the District Commander, the applicant may appeal this decision to the Commandant under § 114.50 of this chapter. The Commandant's determination shall constitute final agency action.

(e) Permit amendments. Applications for amendments to permits will be processed in the same manner as permit applications. The District Commander may approve amendments to any permits which that official is authorized to issue under § 1.01-60(b) of this chapter. All other amendments must be approved by the Commandant.

(a) The General Bridge Act of 1946 requires the approval of the location and plans of bridges prior to start of construction (33 U.S.C. 525). The Commandant has given his advance approval to the location and plans of bridges to be constructed across reaches of waterways navigable in law, but not actually navigated other than by logs, log rafts, rowboats, canoes and small motorboats. In such cases the clearances provided for high water stages will be considered adequate to meet the reasonable needs of navigation.

(b) The term “small motorboats” shall be interpreted in the light of the things and conditions with which it is associated. The term means rowboats, canoes and other similar craft with outboard motors. It does not include sailing or cabin cruiser craft.

(a) All bridges are obstructions to navigation and are tolerated only as long as they serve the needs of land transportation while allowing for the reasonable needs of navigation.

(b) This part describes the general procedures by which the U.S. Coast Guard determines a bridge to be an unreasonable obstruction to navigation and issues an Order to Alter under the authority of the following statutes, as appropriate: Section 18 of the Rivers and Harbors Appropriations Act of 1899, 33 U.S.C. 502; Section 4 of the Bridge Act of 1906, 33 U.S.C. 494; or the Truman-Hobbs Act of 1940, as amended, 33 U.S.C. 511-524.

(c) A bridge constructed across a navigable water of the United States shall not unreasonably obstruct the free navigation of the water over which it was constructed, either due to insufficient height or width of the navigation span, or because of difficulty in passing through the draw opening. If any bridge unreasonably obstructs navigation, the Commandant, U.S. Coast Guard, will order the alteration of that bridge. Alterations may include structural changes, replacement, or removal of the bridge.

(d) Whenever the Coast Guard has good reason to believe that a bridge across any of the navigable waters of the United States is an unreasonable obstruction to navigation, the Coast Guard will give notice to the owner of the bridge and other interested parties, and hold a public hearing at which the interested parties will have a full opportunity to be heard and to offer evidence on the question of whether alterations to the bridge are necessary and, if so, the extent of alterations needed.

(e) If the Coast Guard determines that alterations to a bridge are necessary, the Commandant, U.S. Coast Guard, will issue to the bridge owner an Order to Alter containing details of the alterations necessary to render navigation through or under the bridge reasonably free, easy, and unobstructed.

(1) In the case of a railroad or publicly owned highway bridge, an Order to Alter is issued to the bridge owner under the provisions of the Truman-Hobbs Act (33 U.S.C. 511 et seq.). In ordering these alterations, the Coast Guard will give due regard to the necessities of free and unobstructed navigation and of rail and highway traffic. For alterations to bridges governed by the Truman-Hobbs Act, the Coast Guard must approve general plans, specifications, and contracts for the alteration project, as well as approving the apportionment of the total cost of the alterations between the United States and the bridge owner.

(2) For all other bridges, the Order to Alter will contain the required alterations for the bridge and will prescribe a reasonable time in which to accomplish the required alterations. The bridge owner is responsible for the entire cost of the required alterations.

§ 116.05Complaints.

Any person, company, or other entity may submit to the District Commander of the Coast Guard district in which a bridge over a navigable water of the United States is located, a complaint that a bridge unreasonably obstructs navigation. The complaint must be in writing and include specific details to support the allegation.

§ 116.10Preliminary review.

(a) Upon receipt of a written complaint, the District Commander will review the complaint to determine if, in the District Commander's opinion, the complaint is justified and whether a Preliminary Investigation is warranted.

(1) The District Commander's opinion as to whether or not the complaint warrants a Preliminary Investigation will be formed through informal discussions with the complainant, users of the affected waterway, the owner of the bridge, and other interested parties.

(2) In forming an opinion, the District Commander may also review the district files, records of accidents, and details of any additional written complaints associated with the bridge in question.

(b) In the absence of any written complaint, the District Commander may decide, based on a bridge's accident history or other criteria, to conduct a Preliminary Investigation.

(c) The District Commander will inform the complainant and the Chief, Office of Bridge Administration of the determination of any Preliminary Review. If the District Commander decides that the bridge in question is not an unreasonable obstruction to navigation, the complainant will be provided with a brief summary of the information on which the District Commander based the decision and will be informed of the appeal process described in § 116.55. There will be no further investigation, unless additional information warrants a continuance or reopening of the case.

(a) During the Preliminary Investigation, the District Commander will prepare a written report containing all pertinent information and submit the report, together with a recommendation for or against the necessity of a Detailed Investigation, to the Chief, Office of Bridge Administration.

(b) The Preliminary Investigation Report will include a description of the nature and extent of the obstruction, the alterations to the bridge believed necessary to meet the reasonable needs of existing and future navigation, the type and volume of waterway traffic, and a calculation of the benefits to navigation which would result from the proposed bridge alterations.

(c) The Chief, Office of Bridge Administration will review the Preliminary Investigation Report and make a Preliminary Decision whether or not to undertake a Detailed Investigation and a Public Hearing.

(d) If after reviewing the Preliminary Investigation Report, the Chief, Office of Bridge Administration decides that further investigation is not warranted, the complainant will be notified of the decision. This notification will include a brief summary of information on which the decision was based and details of the appeal process described in § 116.55.

(a) When the Chief, Office of Bridge Administration determines that a Detailed Investigation should be conducted, the District Commander will initiate an investigation that addresses all of the pertinent data regarding the bridge, including information obtained at a public hearing held under § 116.25. As part of the investigation, the District Commander will develop a comprehensive report, termed the “Detailed Investigation Report”, which will discuss: the obstructive character of the bridge in question; the impact of that bridge upon navigation; navigational benefits derived; whether an alteration is needed to meet the needs of navigation; and, if alteration is recommended, what type.

(b) The District Commander will forward the completed Detailed Investigation Report to the Chief, Office of Bridge Administration for review together with a recommendation of whether the bridge should be declared an unreasonable obstruction to navigation and, if so, whether an Order to Alter should be issued.

(a) Any time the Chief, Office of Bridge Administration determines that a Detailed Investigation is warranted, or when Congress declares a bridge unreasonably obstructive, the District Commander will hold a public hearing near the location of the bridge to provide the bridge owner, waterway users, and other interested parties the opportunity to offer evidence and be heard, orally or in writing, as to whether any alterations are necessary to provide reasonably free, safe, and unobstructed passage for waterborne traffic. The District Commander will issue a public notice announcing the public hearing stating the time, date, and place of the hearing.

(b) When a bridge is statutorily determined to be an unreasonable obstruction, the scope of the hearing will be to determine what navigation clearances are needed.

(c) In all other cases, the scope of the hearing will be to address issues bearing on the question of whether the bridge is an unreasonable obstruction to navigation and, if so, what alterations are needed.

(d) The hearing will be recorded. Copies of the public hearing transcript will be available for purchase from the recording service.

(a) Upon receiving a Detailed Investigation Report from a District Commander, the Chief, Office of Bridge Administration will review all the information and make a final determination of whether or not the bridge is an unreasonable obstruction to navigation and, if so, whether to issue an Order to Alter. This determination will be accompanied by a supporting written Decision Analysis which will include a Benefit/Cost Analysis, including calculation of a Benefit/Cost Ratio.

(b) The Benefit/Cost ratio is calculated by dividing the annualized navigation benefit of the proposed bridge alteration by the annualized government share of the cost of the alteration.

(c) Except for a bridge which is statutorily determined to be an unreasonable obstruction, an Order to Alter will not be issued under the Truman-Hobbs Act unless the ratio is at least 1:1.

(d) If a bridge is statutorily determined to unreasonably obstruct navigation, the Chief, Office of Bridge Administration will prepare a Decision Analysis to document and provide details of the required vertical and horizontal clearances and the reasons alterations are necessary.

(e) If the Chief, Office of Bridge Administration decides to recommend that the Commandant issue an Order to Alter, or a bridge is statutorily determined to unreasonably obstruct navigation, the Chief, Office of Bridge Administration will issue a letter to the bridge owner (“The 60-Day Letter”) at least 60 days before the Commandant issues an Order to Alter. This letter will contain the reasons an alteration is necessary, the proposed alteration, and, in the case of a Truman-Hobbs bridge, an estimate of the total project cost and the bridge owner's share.

(f) If the bridge owner does not agree with the terms proposed in the 60-Day Letter, the owner may request a reevaluation of the terms. The request for a reevaluation must be in writing, and identify the terms for which reevaluation is requested. The request may provide additional information not previously presented.

(g) Upon receipt of the bridge owner's response, the Chief, Office of Bridge Administration will reevaluate the situation based on the additional information submitted by the bridge owner. If after the Chief, Office of Bridge Administration reviews the determination, there is no change, the Commandant may issue an Order to Alter as set out in § 116.35. The Chief, Office of Bridge Administration determination based on the reevaluation will constitute final agency action.

(a) If the bridge owner agrees with the contents of the 60-Day Letter, if no reply is received by 60 days after the issuance of the letter, or if after reevaluation a bridge is determined to be an unreasonable obstruction to navigation, the Commandant will issue an Order to Alter.

(1) If a bridge is eligible for funding under the Truman-Hobbs Act, the Order to Alter will specify the navigational clearances to be accomplished in order to meet the reasonable needs of navigation.

(2) An Order to Alter for a bridge that is not eligible for Truman-Hobbs funding will specify the navigational clearances that are required to meet the reasonable needs of navigation and will prescribe a reasonable time in which to accomplish them.

(b) If appropriate, the Order to Alter will be accompanied by a letter of special conditions setting forth safeguards needed to protect the environment or to provide for any special needs of navigation.

(c) If a proposed alteration to a bridge has desirable, non-navigational benefits, the Chief, Office of Bridge Administration may require an equitable contribution from any interested person, firm, association, corporation, municipality, county, or state benefiting from the alteration as a prerequisite to the making of an Order to Alter for that alteration.

(d) Failure to comply with any Order to Alter issued under the provisions of this part will subject the owner or controller of the bridge to the penalties prescribed in 33 U.S.C. 495, 502, 519, or any other applicable provision.

(a) After an Order to Alter has been issued to a bridge owner under the Truman-Hobbs Act, the Chief, Office of Bridge Administration will issue a letter to the bridge owner outlining the owner's responsibilities to submit plans and specifications to the Chief, Office of Bridge Administration for the alteration of the bridge. The plans and specifications, at a minimum, must provide for the clearances identified in the Order to Alter. The plans and specifications may also include any other additional alteration to the bridge that the owner considers desirable to meet the requirements of railroad or highway traffic. During the alteration process, balanced consideration shall be given to the needs of rail, highway, and marine traffic.

(b) The Chief, Office of Bridge Administration will approve or reject the plans and specifications submitted by the bridge owner, in whole or in part, and may require the submission of new or additional plans and specifications.

(c) When Chief, Office of Bridge Administration has approved the submitted plans and specifications, they are final and binding upon all parties, unless later changes are approved by the Chief, Office of Bridge Administration. Any changes to the approved plans will be coordinated with the District Commander.

(a) Once the plans and specifications for a bridge eligible for funding under the Truman-Hobbs Act have been approved, the bridge owner must take bids for the alteration of the bridge consistent with the approved plans and specifications. Those bids must then be submitted to the Chief, Office of Bridge Administration for approval.

(b) After the bridge owner submits the guaranty of cost required by 33 U.S.C. 515, the Chief, Office of Bridge Administration authorizes the owner to award the contract.

(c) Partial payments of the government's costs are authorized as the work progresses to the extent that funds have been appropriated.

(a) In determining the apportionment of costs, the bridge owner must bear such part of the cost attributable to the direct and special benefits which will accrue to the bridge owner as a result of alteration to the bridge, including expected savings in repairs and maintenance, expected increased carrying capacity, costs attributable to the requirements of highway and railroad traffic, and actual capital costs of the used service life. The United States will bear the balance of the costs, including that part attributable to the necessities of navigation.

(b) “Direct and special benefits” ordinarily will include items desired by the owner but which have no counterpart or are of higher quality than similar items in the bridge prior to alteration. Examples include improved signal and fender systems, pro rata share of dismantling costs, and improvements included, but not required, in the interests of navigation.

(c) During the development of the Apportionment of Costs, the bridge owner will be provided with an opportunity to be heard. Proportionate shares of cost to be borne by the United States and the bridge owner are developed in substantially the following form:

Total cost of project ____ $____Less salvage ____ $____Less contribution by third party ____ $____Cost of alteration to be apportioned ____ $____Share to be borne by the bridge owner:Direct and Special Benefits:a. Removing old bridge ____ $____b. Fixed charges ____ $____c. Betterments ____ $____Expected savings in repair or maintenance costs:a. Repair ____ $____b. Maintenance ____ $____Costs attributable to requirements of railroad and/or highway traffic ____ $____Expenditure for increased carrying capacity ____ $____Expired service life of old bridge ____ $____Subtotal ____ $____Share to be borne by the bridge owner ____ $____Contingencies ____ $____Total ____ $____Share to be borne by the United States ____ $____Contingencies ____ $____Total ____ $____

(d) The Order of Apportionment of Costs will include the guaranty of costs.

§ 116.55Appeals.

(a) Except for the decision to issue an Order to Alter, if a complainant disagrees with a recommendation regarding obstruction or eligibility made by a District Commander, or the Chief, Office of Bridge Administration, the complainant may appeal that decision to the Assistant Commandant for Operations.

(b) The appeal must be submitted in writing to the Assistant Commandant for Operations, U.S. Coast Guard, 2100 Second Street, SW., Washington, DC 20593-0001, within 60 days after the District Commander's or the Chief's, Office of Bridge Administration decision. The Assistant Commandant for Operations will make a decision on the appeal within 90 days after receipt of the appeal. The Assistant Commandant for Operations' decision of this appeal shall constitute final agency action.

(c) Any Order of Apportionment made or issued under section 6 of the Truman-Hobbs Act, 33 U.S.C. 516, may be reviewed by the Court of Appeals for any judicial circuit in which the bridge in question is wholly or partly located, if a petition for review is filed within 90 days after the date of issuance of the order. The review is described in section 10 of the Truman-Hobbs Act, 33 U.S.C. 520. The review proceedings do not operate as a stay of any order issued under the Truman-Hobbs Act, other than an order of apportionment, nor relieve any bridge owner of any liability or penalty under other provisions of that act.

Subpart A—General Requirements§ 117.1Purpose.

This subpart prescribes general requirements relating to the use and operation of drawbridges across the navigable waters of the United States.

Note:

The primary jurisdiction to regulate drawbridges across the navigable waters of the United States is vested in the Federal Government. Laws, ordinances, regulations, and rules which purport to regulate these bridges and which are not promulgated by the Federal Government have no force and effect.

§ 117.3Applicability.

The provisions of this subpart not in conflict with the provisions of Subpart B apply to each drawbridge.

Note:

For all of the requirements applicable to a drawbridge listed in Subpart B, one must review the requirements in Subpart A and §§ 117.51 through 117.99 of Subpart B, as well as the requirements in Subpart B applicable to the particular drawbridge in question.

§ 117.4Definitions.

Certain terms used in this part are defined in this section.

Appurtenance. The term “appurtenance” means an attachment or accessory extending beyond the hull or superstructure that is not an integral part of the vessel and is not needed for a vessel's piloting, propelling, controlling, or collision avoidance capabilities.

Lowerable. The term “lowerable” means the nonstructural vessel appurtenance can be mechanically or manually lowered and raised again. The term “lowerable” also applies to a nonstructural vessel appurtenance which can be modified to make the item flexible, hinged, collapsible, or telescopic such that it can be mechanically or manually lowered and raised again. Failure to make the modification is considered equivalent to refusing to lower a lowerable nonstructural appurtenance that is not essential to navigation. Examples of appurtenances which are considered to be lowerable include, but are not limited to, fishing outriggers, radio antennae, television antennae, false stacks, and masts purely for ornamental purposes. Examples of appurtenances which are not considered to be lowerable include, but are not limited to, radar antennae, flying bridges, sailboat masts, piledriver leads, spud frames on hydraulic dredges, drilling derricks' substructures and buildings, cranes on drilling or construction vessels, or other items of permanent and fixed equipment.

Nonstructural. The term “nonstructural” means that the item is not rigidly fixed to the vessel and is thus susceptible to relocation or alteration.

Not essential to navigation. The term “not essential to navigation” means the nonstructural vessel appurtenance does not adversely affect the vessel's piloting, propulsion, control, or collision avoidance capabilities when in the lowered position.

Except as otherwise required by this subpart, drawbridges shall open promptly and fully for the passage of vessels when a request to open is given in accordance with this subpart.

Editorial Note:

For Federal Register citations relating to temporary deviations from the regulatory provisions in § 117.5, see the List of CFR Sections Affected, which appears in the Finding Aids section of the printed volume and on GPO Access.

§ 117.7General duties of drawbridge owners and tenders.

(a) Drawbridge owners and tenders shall operate the draw in accordance with the requirement in this part.

(b) Except for drawbridges not required to open for the passage of vessels, owners of drawbridges shall ensure that:

(1) The necessary drawtenders are provided for the safe and prompt opening of the draw;

(2) The operating machinery of the draw is maintained in a serviceable condition; and.

(3) The draws are operated at sufficient intervals to assure their satisfactory operation.

§ 117.9Delaying opening of a draw.

No person shall unreasonably delay the opening of a draw after the signals required by § 117.15 have been given.

Note:

Trains are usually controlled by the block method. That is, the track is divided into blocks or segments of a mile or more in length. When a train is in a block with a drawbridge, the draw may not be able to open until the train has passed out of the block and the yardmaster or other manager has “unlocked” the drawbridge controls. The maximum time permitted for delay is defined in Subpart B for each affected bridge. Land and water traffic should pass over or through the draw as soon as possible in order to prevent unnecessary delays in the opening and closure of the draw.

§ 117.11Unnecessary opening of the draw.

No vessel owner or operator shall—

(a) Signal a drawbridge to open if the vertical clearance is sufficient to allow the vessel, after all lowerable nonstructural vessel appurtenances that are not essential to navigation have been lowered, to safely pass under the drawbridge in the closed position; or

(b) Signal a drawbridge to open for any purpose other than to pass through the drawbridge opening.

[CGD 91-059, 59 FR 16563, Apr. 7, 1994]§ 117.15Signals.

(a) General. (1) The operator of each vessel requesting a drawbridge to open shall signal the drawtender and the drawtender shall acknowledge that signal. The signal shall be repeated until acknowledged in some manner by the drawtender before proceeding.

(2) The signals used to request the opening of the draw and to acknowledge that request shall be sound signals, visual signals, or radiotelephone communications described in this subpart.

(3) Any of the means of signaling described in this subpart sufficient to alert the party being signaled may be used.

(b) Sound signals. (1) Sound signals shall be made by whistle, horn, megaphone, hailer, or other device capable of producing the described signals loud enough to be heard by the drawtender.

(2) As used in this section, “prolonged blast” means a blast of four to six seconds duration and “short blast” means a blast of approximately one second duration.

(3) The sound signal to request the opening of a draw is one prolonged blast followed by one short blast sounded not more than three seconds after the prolonged blast. For vessels required to be passed through a draw during a scheduled closure period, the sound signal to request the opening of the draw during that period is five short blasts sounded in rapid succession.

(4) When the draw can be opened immediately, the sound signal to acknowledge a request to open the draw is one prolonged blast followed by one short blast sounded not more than 30 seconds after the requesting signal.

(5) When the draw cannot be opened immediately, or is open and shall be closed promptly, the sound signal to acknowledge a request to open the draw is five short blasts sounded in rapid succession not more than 30 seconds after the vessel's opening signal. The signal shall be repeated until acknowledged in some manner by the requesting vessel.

(c) Visual signals. (1) The visual signal to request the opening of a draw is—

(i) A white flag raised and lowered vertically; or

(ii) A white, amber, or green light raised and lowered vertically.

(2) When the draw can be opened immediately, the visual signal to acknowledge a request to open the draw, given not more than 30 seconds after the vessel's opening signal, is—

(i) A white flag raised and lowered vertically;

(ii) A white, amber, or green light raised and lowered vertically; or

(iii) A fixed or flashing white, amber, or green light or lights.

(3) When the draw cannot be opened immediately, or is open and must be closed promptly, the visual signal to acknowledge a request to open the draw is—

(i) A red flag or red light swung back and forth horizontally in full sight of the vessel given not more than 30 seconds after the vessel's opening signal; or

(ii) A fixed or flashing red light or lights given not more than 30 seconds after the vessel's opening signal.

(4) The acknowledging signal when the draw cannot open immediately or is open and must be closed promptly shall be repeated until acknowledged in some manner by the requesting vessel.

(d) Radio telephone communications. (1) Radiotelephones may be used to communicate the same information provided by sound and visual signals.

Note:

Call signs and radio channels for drawbridges with radiotelephones are listed in Appendix A to this part.

(2) The vessel and the drawtender shall monitor the frequency used until the vessel has cleared the draw.

(3) When radiotelephone contact cannot be initiated or maintained, sound or visual signals under this section shall be used.

When a vessel must past two or more drawbridges close together, the opening signal is given for the first bridge. After acknowledgment from the first bridge that it will promptly open, the opening signal is given for the second bridge, and so on until all bridges that the vessel must pass have been given the opening signal and have acknowledged that they will open promptly.

§ 117.19Signalling when two or more vessels are approaching a drawbridge.

When two or more vessels are approaching the same drawbridge at the same time, or nearly the same, time, whether from the same or opposite directions, each vessel shall signal independently for the opening of the draw and the drawtender shall reply in turn to the signal of each vessel. The drawtender need not reply to signals by vessels accumulated at the bridge for passage during a scheduled open period.

§ 117.21Signalling for an opened drawbridge.

When a vessel approaches a drawbridge with the draw in the open position, the vessel shall give the opening signal. If no acknowledgment is received within 30 seconds, the vessel may proceed, with caution, through the open draw.

§ 117.23Installation of radiotelephones.

(a) When the District Commander deems it necessary for reasons of safety of navigation, the District Commander may require the installation and operation or a radiotelephone on or near a drawbridge.

(b) The District Commander gives written notice of the proposed requirement to the bridge owner.

(c) All comments the owner wishes to submit shall be submitted to the District Commander within 30 days of receipt of the notice under paragraph (b) of this section.

(d) If, upon consideration of the comments received, the District Commander determines that a radiotelephone is necessary, the District Commander notifies the bridge owner that a radiotelephone shall be installed and gives a reasonable time, not to exceed six months, to install the radiotelephone and commence operation.

§ 117.24Radiotelephone installation identification.

(a) The Coast Guard authorizes, and the District Commander may require the installation of a sign on drawbridges, on the upstream and downstream sides, indicating that the bridge is equipped with and operates a VHF radiotelephone in accordance with § 117.23.

(b) The sign shall give notice of the radiotelephone and its calling and working channels—

(1) In plain language; or

(2) By a sign consisting of the outline of a telephone handset with the long axis placed horizontally and a vertical three-legged lightning slash superimposed over the handset. The slash shall be as long vertically as the handset is wide horizontally and normally not less than 27 inches and no more than 36 inches long. The preferred calling channel should be shown in the lower left quadrant and the preferred working channel should be shown in the lower right quadrant.

Note:

It is recommended that the radiotelephone sign be similar in design to the Service Signs established by the Federal Highway Administration (FHWA) in U.S. Road Symbol Signs using Reflective Blue and Reflective White colors. Color and design information is available from the District Commander of the Coast Guard District in which the bridge is located.

(a) When a drawtender is informed by a reliable source that an emergency vehicle is due to cross the draw, the drawtender shall take all reasonable measures to have the draw closed at the time the emergency vehicle arrives at the bridge.

(b) When a drawtender receives notice, or a proper signal as provided in § 117.15 of this part, the drawtender shall take all reasonable measures to have the draw opened, regardless of the operating schedule of the draw, for passage of the following, provided this opening does not conflict with local emergency management procedures which have been approved by the cognizant Coast Guard Captain of the Port:

(1) Federal, State, and local government vessels used for public safety;

(2) Vessels in distress where a delay would endanger life or property;

Drawbridges need not open for the passage of vessels during periods of natural disasters or civil disorders declared by the appropriate authorities unless otherwise provided for in Subpart B or directed to do so by the District Commander.

§ 117.35Operations during repair or maintenance.

(a) When operation of the draw must deviate from the regulations in this part for scheduled repair or maintenance work, the drawbridge owner shall request approval from the District Commander at least 30 days before the date of the intended change. The request shall include a brief description of the nature of the work to be performed and the times and dates of requested changes. The District Commander's decision is forwarded to the applicant within five working days of the receipt of the request. If the request is denied, the reasons for the denial are forwarded with the decision.

(b) When the draw is rendered inoperative because of damage to the structure or when vital, unscheduled repair or maintenance work shall be performed without delay, the drawbridge owner shall immediately notify the District Commander and give the reasons why the draw is or should be rendered inoperative and the expected date of completion of the repair or maintenance work.

(c) All repair or maintenance work under this section shall be performed with all due speed in order to return the draw to operation as soon as possible.

(d) If the operation of the draw will be affected for periods of less than 60 days, the regulations in this part will not be amended. Where practicable, the District Commander publishes notice of the temporary deviations from the regulations in this part in the Federal Register and Local Notices to Mariners. If operation of the draw is expected to be affected for more than 60 days, the District Commander publishes temporary regulations covering the repair period.

§ 117.37Opening or closure of draw for public interest concerns.

(a) For reasons of public health or safety or for public functions, such as street parades and marine regattas, the District Commander may authorize the opening or closure of a drawbridge for a specified period of time.

(b) Requests for opening or closure of a draw shall be submitted to the District Commander at least 30 days before the proposed opening or closure and include a brief description of the proposed event or other reason for the request, the reason why the opening or closure is required, and the times and dates of the period the draw is to remain open or closed.

(c) Approval by the District Commander depends on the necessity for the opening or closure, the reasonableness of the times and dates, and the overall effect on navigation and users of the bridge.

§ 117.39Closure of draw due to infrequent use.

Upon written request by the owner or operator of a drawbridge, the District Commander may, after notice in the Federal Register and opportunity for public comment, permit the draw to be closed and untended due to infrequency of use of the draw by vessels. The District Commander may condition approval on the continued maintenance of the operating machinery.

§ 117.41Maintenance of draw in fully open position.

The draw may be maintained in the fully open position to permit the passage of vessels and drawtender service discontinued if the District Commander is notified in advance. The draw shall remain in the fully open position until drawtender service is restored or authorization under § 117.39 is given for the draw to remain closed and untended.

In order to evaluate suggested changes to the drawbridge operation requirements, the District Commander may authorize temporary deviations from the regulations in this part for periods not to exceed 90 days. Notice of these deviations is disseminated in the Local Notices to Mariners and published in the Federal Register.

(b) Except for provisions in this part which specify otherwise for particular drawbridges, clearance gauges shall be designed, installed, and maintained according to the provisions of § 118.160 of this chapter.

Note:

Clearance gauge requirements, if any, for drawbridges other than those referred to in this section are listed in Subpart B under the appropriate bridge.

(a) Complaints of alleged violations under this part are submitted to the District Commander of the Coast Guard District in which the drawbridge is located.

(b) Penalties for violations under this part are assessed and collected under Subpart 1.07 of Part 1 of this chapter.

Subpart B—Specific Requirements§ 117.51Purpose.

This subpart prescribes specific requirements relating to the operation of certain drawbridges.

Note:

The drawbridges under this subpart are listed by the waterway they cross and by the state in which they are located. Waterways are arranged alphabetically by state. The drawbridges listed under a waterway are generally arranged in order from the mouth of the waterway moving upstream. The drawbridges on the Atlantic Intracoastal Waterway are listed from north to south and on the Gulf Intracoastal Waterway from east to west.

§ 117.53Applicability.

(a) The requirements in this subpart apply to the bridges listed and are in addition to, or vary from, the general requirements in Subpart A.

(b) A requirement in this subpart which varies from a general requirement in Subpart A supersedes the general requirement.

(c) All other general requirements in Subpart A not at variance apply to the bridges listed in this subpart.

(d) The draws of a number of the bridges listed in this subpart need not open for the passage of vessels during certain periods, however, this does not preclude the bridge owner from directing the drawtender to open the draw during these periods.

§ 117.55Posting of requirements.

(a) The owner of each drawbridge under this subpart, other than removable span bridges, shall ensure that a sign summarizing the requirements in this subpart applicable to the bridge is posted both upstream and downstream of the bridge. The requirements to be posted need not include those in Subpart A or §§ 117.51 through 117.99.

(b) The signs shall be of sufficient size and so located as to be easily read at any time from an approaching vessel.

(c) If advance notice is required to open the draw, the signs shall also state the name, address, and telephone number of the person to be notified.

§ 117.57Advance notice.

Owners and tenders of drawbridges requiring advance notice to open shall use all reasonable means to open the draw at the requested time and give due regard to the possibility that a brief delay may be experienced by the vessel giving the advance notice.

§ 117.59Special requirements due to hazards.

For the duration of occurrences hazardous to safety or navigation, such as floods, freshets, and damage to the bridge or fender system, the District Commander may require the owner of an operational drawbridge listed in this subpart to have the bridge attended full time and open on signal.

§ 117.123Arkansas Waterway-Automated Railroad Bridges.

(a) Across the Arkansas River, the draw of the Cotton Belt Railroad (Rob Roy) Bridge, Mile 67.4, is maintained in the closed position and is remotely operated. The following signals shall be used:

(1) The opening signal from the vessel for each of these bridges is three short blasts.

(2) The acknowledging signal is flashing white lights visible upstream and downstream. When the operator of the vessel sights the acknowledging signal, one prolonged blast shall be sounded.

(3) This signal is acknowledged by the bridge controller when the draw is to open by changing the flashing white lights to continuous white lights, and sounding one blast on a horn. When the span is fully raised to a maximum clearance of 52 feet, the navigation lights at mid channel change from red to green, indicating that the draw is ready for passage.

(4) If the draw cannot open, flashing amber warning lights are flashed and four blasts are sounded, indicating that a train is approaching or that maintenance work is in progress.

(5) The vessel shall acknowledge that there is a delay by sounding four short blasts.

(6) When the draw opens (after the train crosses or when maintenance work permits), the amber lights are turned off, the continuous white lights turned on, and one blast sounded, to indicate the draw is ready for passage.

(7) The vessel acknowledges with one blast and, after the draw is fully open, may proceed through the draw.

(8) When the vessel clears the draw, the mid channel navigation light changes from green to red, the amber warning lights will flash, and, after one minute, the draw lowers and locks.

(b) The draws of the Junction Railroad Bridge at mile 118.7 and the Baring Cross Railroad Bridge at mile 119.6, Arkansas River, at Little Rock, are maintained in the closed position and are remotely operated. The draw of the Rock Island Railroad Bridge at mile 118.2, Arkansas River, at Little Rock, is maintained in the open position. Use the following procedures to request opening of these bridges when necessary for transit;

(1) Normal Flow Procedures. Any upbound or downbound vessel which requires opening the draw of any of these bridges shall establish contact by radiotelephone with the remote drawbridge operator on VHF-FM Channel 13 in North Little Rock, Arkansas. The remote drawbridge operator will advise the vessel whether the requested span can be immediately opened and maintain constant contact with the vessel until the requested span has opened and the vessel passage has been completed. If any or all of the drawbridges cannot be opened immediately, the remote drawbridge operator will notify the calling vessel and provide an estimated time for individual drawbridge openings.

(2) High Velocity Flow Procedures. The area from mile 118.2 to mile 125.4 is a regulated navigation area (RNA) as described in 33 CFR 165.817. During periods of high velocity flow, which is defined as a flow rate of 70,000 cubic feet per second or greater at the Murray Lock and Dam, mile 125.4, downbound vessels which require that the draw of these three bridges be opened for unimpeded passage shall contact the remote drawbridge operator on VHF-FM Channel 13 either before departing Murray Lock and Dam, or before departing the mooring cells at Mile 121.5 to ensure that the Rock Island, Junction, and Baring Cross Railroad drawbridges are opened. The remote drawbridge operator shall immediately respond to the vessel's call, ensure that all three drawbridges are open for pasage, and ensure that they remain in the open position until the downbound vessel has passed through each drawbridge. If a closed drawbridge cannot be opened immediately for unimpeded passage in accordance with 33 CFR 163.203, the remote drawbridge operator will immediately notify the downbound vessel and provide an estimated time for drawbridge openings. Upbound vessels shall request openings in accordance with the normal flow procedures as set forth above. The remote drawbridge operator shall keep all approaching vessels informed of the position of the drawbridge spans.

(c) The draw of the Arkansas Missouri Railroad Bridge, Mile 300.8 Arkansas River at Van Buren, and the Missouri Pacific Railroad Drawbridge, Mile 7.5 Arkansas Waterway at Benzal, are maintained in the open position with a minimum vertical clearance of 52 feet except as follows:

(1) When a train approaches either bridge, amber lights attached to the bridge begin to flash and an audible signal on the bridge sounds. At the end of 10 minutes, the amber light continues to flash; however, the audible signal stops and the draw lowers and locks if the photoelectric boat detection system detects no obstruction under the span. If there is an obstruction, the draw opens to its full height until obstruction is cleared.

(2) After the train clears the bridge, the draw opens to its full height, the amber flashing light stops, and the mid channel lights change from red to green, indicating the navigation channel is open for the passage of vessels.

(1) The draw is normally maintained in the fully open position, displaying a green light to indicate that vessels may pass.

(2) When a vessel is approaching and the draw is in the open position, contact shall be established by radiotelephone with the remote operator to assure that the draw remains open until passage is complete.

(3) When a vessel is approaching and the draw is in the closed position, contact shall be established by radiotelephone with the remote operator. If the draw cannot be opened immediately, alternate flashing red lights are displayed. If the draw can be opened immediately, flashing amber lights are displayed.

(4) When a train approaches the bridge and the draw is in the open position, the operator shall activate alternate flashing red lights on top of the draw, sound four short blasts, and scan the river on radar to determine whether any vessel is approaching the bridge. The remote operator shall also broadcast that the draw is closing. If a vessel or vessels are approaching the bridge within one mile, as determined by radar scanning, response to radio broadcast, or electronic detector, the flashing red lights shall be changed to flashing amber and the operator shall keep the draw in the fully open position until the vessel or vessels have cleared the bridge. If no vessel is approaching the bridge or is beneath the draw, the draw may be lowered and locked in place.

(5) After the train has cleared the bridge, the draw shall be raised to its full height and locked in place, the red flashing lights stopped, and the draw lights changed from red to green.

(b) The draw of the Union Pacific railroad bridge, Mile 151.2, at Pekin, Illinois, is operated by a remote operator located at the Union Pacific offices in Chicago, Illinois, as follows:

(1) The draw is normally maintained in the fully open position, displaying green mid-channel lights to indicate that the span is fully open.

(2) The draw is equipped with the following:

(i) A radiotelephone link direct to the remote operator;

(ii) A horn for sound signals;

(iii) Eight high intensity amber warning lights, oriented upstream and downstream, with two secured to the uppermost chord and two secured to the lowermost chord of the drawspan;

(iv) A radar antenna on the lower portion of the drawspan capable of scanning one mile upstream and one mile downstream; and

(v) Infrared scanners located on the upstream and downstream ends of the channel span piers, to detect vessels or other obstructions under the bridge.

(3) The remote operator shall maintain a radiotelephone watch for mariners to establish contact as they approach the bridge to ensure that the draw is open or that it remains open until passage is complete.

(4) When a train approaches the bridge and the draw is in the open position, the remote operator initiates a ten minute warning period before closing the bridge. During this warning period, the amber lights begin flashing and a signal of four short blasts sounds on a horn. The four-blast signal will repeat after a five second interval. A synthesized-voice message is broadcast over the radiotelephone as follows: “The Union Pacific railroad bridge at Mile 151.2, Illinois River, will close to navigation in ten minutes.” The announcement is repeated every two minutes, counting down the time remaining until closure.

(5) At the end of the ten minute warning period, the remote bridge operator scans under the bridge using infrared detectors and the upstream and downstream approaches to the bridge using radar to determine whether any vessels are under or are approaching the bridge. If any vessels are under or are approaching the bridge within one mile as determined by infrared or radar scanning or by a radiotelephone response, the remote operator shall not close the bridge until the vessel or vessels have cleared the bridge.

(6) If no vessels are under or approaching the bridge, the mid-channel navigation lights will change from green to red, the horn signal of four short blasts will sound, twice, and the radiotelephone message will change to: “The Union Pacific Railroad Bridge at Mile 151.2, Illinois River, is closed to navigation.” The message will repeat every two minutes and the amber lights will continue to flash until the bridge is fully reopened.

(7) If the infrared scanners detect a vessel or other obstruction under the bridge before the drawspan is fully lowered and locked, the closing sequence is stopped, automatically, and the drawspan is raised to its fully open position until the channel is clear. When obstruction has cleared the navigation span, the remote operator confirms that the channel is clear, and reinitiates the ten-minute warning cycle.

(8) After the train has cleared the bridge, the remote operator initiates the lift span raising cycle. When the draw is raised to its full height and locked in place, the flashing lights stop and the mid-channel navigation lights change from red to green. The synthesized voice announcement broadcasts at two minute intervals for ten minutes that the bridge is reopened to navigation.

(c) The draws of the McDonough Street Bridge, mile 287.3; Jefferson Street bridge, mile 287.9; Cass Street bridge, mile 288.1; Jackson Street bridge, mile 288.4; and Ruby Street bridge, mile 288.7; all of Joliet, shall open on signal, except that they need not open from 7:30 a.m. to 8:30 a.m. and from 4:15 p.m. to 5:15 p.m. Monday through Saturday.

(1) The drawspan is normally maintained in the fully open to navigation position displaying green center span navigation lights to indicate that the drawspan is fully open.

(2) The bridge is equipped with the following:

(i) A radiotelephone link direct to the remote operator;

(ii) A radar antenna on top of the drawspan capable of scanning the river, one mile upstream and one mile downstream;

(iii) Infrared boat detectors under the drawspan, to allow the remote bridge operator to detect vessels under the drawspan;

(iv) Electronic motion detectors under the drawspan to allow the remote bridge operator to detect vessel movement under the drawspan;

(v) A siren for sound signals; and

(vi) Red and green center span navigation lights.

(3) The remote bridge operator shall maintain a 24 hour VHF marine radio watch for mariners to establish contact as they approach the bridge to ensure that the drawspan is open or that it remains open until passage of river traffic is complete.

(4) When rail traffic approaches the bridge, and the drawspan is in the open position, the remote bridge operator initiates a one minute warning period before closing the drawspan. During this warning period, the remote operator shall broadcast at least twice, via marine radio, that: “The drawspan of the EJ&E Railroad bridge will be lowered in one minute.” A siren on the bridge sounds for 20 seconds, to warn anyone on or under the bridge that the drawspan will be lowered.

(5) If a vessel is approaching the bridge upbound or, departing the Lockport Lock and Dam at mile 291.1, downbound, with intentions of passing through the drawspan, they shall respond to the remote bridge operators' marine radio broadcast, or initiate radio contact, indicating their proximity to the bridge and requesting an opening of the drawspan or that the drawspan remain open until the vessel passes. If any approaching vessel is detected or if a radiotelephone response is received, the remote operator shall not close the drawspan until the vessel or vessels have cleared the bridge.

(6) At the end of the one minute warning period, if no river traffic is approaching or under the drawspan, the remote bridge operator may begin lowering the drawspan. Navigation lights located at the center of the drawspan change from green to red when the drawspan is not in the fully open to navigation position. The drawspan takes approximately 90 seconds to lower.

(7) If the presence of a vessel or other obstruction is discovered approaching or under the drawspan, during the lowering sequence, before the drawspan is fully lowered and locked, the drawspan shall be stopped and raised to the fully open position. When the vessel or obstruction has cleared the drawspan, the remote operator shall confirm that the channel is clear and reinitiate the one minute warning cycle before lowering the drawspan.

(8) If no marine traffic is present the drawspan may be lowered and seated. When the drawspan is lowered and locked in the closed to navigation position, the remote bridge operator periodically broadcasts, via marine radio, that: “The drawspan of the EJ&E Railroad bridge is closed to navigation.”

(10) when rail traffic has cleared the bridge, the remote bridge operator shall raise the drawspan to the fully open to navigation position.

Each swing span of every through swing bridge shall be lighted with three lanterns so that when viewed from an approaching vessel the swing span when closed will display three red lights on top of the span structure, one at each end of the span on the same level and one at the center of the span no less than 10 feet above the other two lights, and when open for navigation will display three green lights on top of the span structure in a line parallel to and directly above the long axis of the span, one at each end of the span on the same level, and one at the center of the span no less than 10 feet above the other two lights. Each lantern shall show through alternate red and green horizontal arcs of 60° each, the axis of adjacent arcs to be 90° from each other; each light shall be securely mounted with the axis of the green arcs parallel to the long axis of the swing span.

(b) Swing span lights on deck and half-through bridges. Each swing span of every deck, half-through, girder, or similar type swing bridge shall be lighted with four lanterns so that when viewed from an approaching vessel the swing span when closed will display one red light at each end, and when open to navigation will display two green lights from each end. Each lantern shall show through one red and two green horizontal arcs of 60° each, the axis of each green arc to be 90° from the axis of the red arc; each light shall be securely mounted at the floor level of the span as near to the side of the span as practicable with the axis of the red light normal to the long axis of the swing span and so that the red light will be visible from an approaching vessel when the span is closed.

(c) Pier lights. Every swing bridge shall be lighted so that each end of the piers adjacent to the navigable channel (draw piers) or each end of their protection piers (draw pier protection piers) and each end of the piers protecting the pivot pier (pivot protection pier) will be marked by a red light. Each of these lights shall show through a horizontal arc of 180° and shall be mounted as low as practicable below the floor level of the swing span to show 90° on either side of a line parallel to the axis of the channel so as to be visible from an approaching vessel.

(d) Axis lights. Every swing bridge shall be lighted so that the intersection of the bridge axis with each side of the pivot pier and the channel side of each draw pier which has a protection pier will be marked by a red light: Provided, That if the draw and draw protection piers are straight along their channel faces these lights shall not be required. Each such light shall show through a horizontal arc of 180°, and shall be mounted on the navigable channel face of the pier as low as practicable below the floor level of the swing span to show 90° either side of a line normal to the axis of the navigable channel so as to be visible from an approaching vessel.

(e) Omission of lights. Where the permanent navigable channel passes on only one side of the pivot pier of any swing span, the District Commander may authorize the omission of lighting of the unused channel.

§ 118.75Lights on single-opening drawbridges.

(a) Bridges in this class. Bridges of the folding, pontoon and similar type single opening drawbridges are included in this class.

(b) Draw span lights. Each draw span of every single opening drawbridge shall be lighted with two lanterns so that when viewed from an approaching vessel the draw span when closed will display two red lights, one at each end of the span and when open to navigation will display two green lights, one at each end of the span. Each lantern shall show alternate red and green horizontal arcs of 60° each, the axis of adjacent arcs to be located 90° from each other; each lantern shall be securely mounted 15 feet above the roadway with the axis of the green arcs parallel to the long axis of the swing span.

(c) Pier or abutment lights. Every swing bridge shall be lighted so that the end of each pier, abutment or fixed portion of the bridge adjacent to the navigable channel through the draw, or each end of the protection piers for such piers, abutments, or fixed portion of the bridge will be marked by a red light. Each red light shall show through an arc of 180°, and shall be securely mounted on the pier, abutment or fixed portion of the bridge as low as practicable to show 90° on either side of a line parallel to the axis of the channel so as to be visible from an approaching vessel.

§ 118.80Lights on bascule bridges.

(a) Lift span lights. Each lift span of every bascule bridge shall be lighted so that the free end of the span will be marked on each side by a green light which shows only when the span is fully open for the passage of a vessel and by a red light which shows for all other positions of the lift span. Each red and each green light shall show through a horizontal arc of 180°. The lighting apparatus shall be securely mounted to the side of the span so that the light will show equally on either side of a line parallel to the axis of the channels, so that they will be visible from an approaching vessel.

Note:

Until such time that major repairs to or replacement of lift span navigation lights are made, existing lights may show through a horizontal arc of less than 180°. When major repairs to or replacement of existing lights are made they shall conform with this paragraph.

(b) Multiple parallel lift span lights. The outermost side of each outer span of every bascule bridge with parallel multiple lifts shall be lighted as prescribed in paragraph (a) of this section; the lights shall be controlled so that the green lights will be displayed only when all spans are open for navigation. The inner sides of each outer lift span and both sides of each inner lift span of such bascule bridge shall be lighted by red lights for all positions of the lift span. These lights shall have the same arcs of illumination and shall be mounted as described in paragraph (a) of this section.

(c) Pier lights. Every bascule bridge shall be lighted so that each end of every pier, or protection pier where provided, in or adjacent to the navigable channels under the lift span or spans will be marked by a red light. Each such red light shall show through a horizontal arc of 180°, and shall be securely mounted as low as practicable on the end of the pier, or protection pier, to show 90° either side of a line parallel to the axis of the navigable channel so as to be visible from an approaching vessel.

(d) Axis lights. Every bascule bridge which has at least one pier provided with a protection pier shall be lighted so that the intersection of the long axis of the lift span with the channel side of each pier, or protection pier, will be marked by a red light: Provided, That if all such piers and protection piers are straight along their channel faces these lights shall not be required. Each such red light shall show through a horizontal arc of 180° and shall be securely mounted on the navigable channel face of the pier as low as practicable to show 90° on either side of a line normal to the axis of the navigable channel so as to be visible from an approaching vessel.

(a) Lift span lights. The vertical lift span of every vertical lift bridge shall be lighted so that the center of the navigable channel under the span will be marked by a range of two green lights when the vertical lift span is open for navigation, and by one red light on each side for all other positions of the lift span. The green lights shall each show through a horizontal arc of 360°; they shall be securely mounted just below the outermost edge of the bridge span structure so as to be visible from an approaching vessel. Each red light shall show through a horizontal arc of 180°, and shall be securely mounted just below the outermost edge of the lift span to show 90° on either side of the line parallel to the axis of the channel so that only one such light will be visible from an approaching vessel.

Note:

Until such time that major repairs to or replacement of lift span navigation lights are made, it is permitted that these lights show through a horizontal arc of not more than 60°. When major repairs to or replacement of such existing lights are made they shall conform with this paragraph.

(b) Pier lights. Every vertical lift bridge shall be lighted so that each end of every pier in or adjacent to navigable channels under the lift span, or each end of every protection pier when provided, will be marked by a red light. Each such light shall show through a horizontal arc of 180°, and shall be securely mounted as low as practicable on the end of the pier, or the protection pier, to show 90° on either side of a line parallel to the axis of the navigable channel so as to be visible from an approaching vessel.

(c) Axis lights. Every lift bridge which has at least one pier provided with a protection pier shall be lighted so that the intersection of the lift span axis with the channel side of each pier adjacent to the navigable channel will be marked by a red light: Provided, That if every such pier, or protection pier, is straight along its channel face these lights shall not be required. Each such light shall show through a horizontal arc of 180°, and shall be securely mounted on the navigable channel face of the pier as low as practicable to show 90° on either side of a line normal to the axis of the navigable channel so as to be visible from an approaching vessel.

Bridges crossing a body of water at an angle other than 90° with the axis of the channel shall be lighted in accordance with the regulations in this part with such modifications as are necessary in each particular case.

§ 118.95Lights on structures not part of a bridge or approach structure.

Lights on sheer booms, isolated piers, obstructions, and other structures not part of a bridge or approach structure must meet the requirements for aids to navigation in Subpart 66.01 of Part 66 of this chapter.

The District Commander may require or authorize the display of high intensity red or green retroreflective panels when the District Commander finds it necessary:

(a) To better identify a hazardous pier.

(b) To provide a backup for red pier lights, red channel margin lights, and green mid channel lights, which are subject to vandalism or otherwise difficult to properly maintain. If the District Commander determines that the nominal nighttime visibility required is less than one-half mile, the panels must be at least six inches square. If the visibility required is more than one-half mile, the panels must be at least 12 inches square.

(c) To mark bridge piers or channel sides on bridges not required to have bridge lighting. Lateral significant red triangles and green square retroreflective panels shall be used. The panels shall be at least 36 square inches in area to provide a nominal nighttime visibility distance of at least one-half mile.

(a) The District Commander may require or authorize the marking of the margins of navigation channels through bridges with U.S. aids to navigation system lateral marks and lights installed on the superstructure or on the channel piers. The District Commander may also require or authorize the use of quick flashing, flashing, isophase or occulting red and green lights to mark the main channels.

(b) If lateral system lights are required or authorized to mark the main navigation channels, fixed yellow lights shall be used to mark the adjacent piers and the centerline of the channel shall be marked with the standard lateral system safe water mark and occulting white light, instead of the lights prescribed in § 118.65.

(c) The District Commander may require or authorize the marking of the centerline of the navigation channel drawspan of floating drawbridges with a special mark, diamond in shape, yellow in color, and with a high intensity retroreflective material border. The District Commander may require or authorize the mark to exhibit a flashing yellow light Morse Code “B” characteristic. The mark may not be visible when the drawspan is in the open position.

The District Commander may require or authorize the installation of radar reflectors and racons on bridge structures, stakes, or buoys. Radar reflectors are used to mark the location of the edge of the navigation channel or bridge channel piers. Racons are used to mark the centerline of the channel.

[CGD 84-022, 51 FR 16313, May 2, 1986]§ 118.130Fog signals.

On waterways where visibility is frequently reduced due to fog or other causes, the District Commander may require or authorize the installation of one or more fog signals to warn the navigator of the presence of the bridge. The fog signals must conform to the installation, range, and sound frequencies provisions in Subpart 67.10 of Part 67 of this chapter. If more than one fog signal is installed on a bridge or in the vicinity, their characteristics must be different to distinguish each signal. The fog signals must be directional to the fullest extent possible to minimize adverse impact on local residents.

[CGD 84-022, 51 FR 16313, May 2, 1986]§ 118.140Painting bridge piers.

The District Commander may require painting the sides of bridge channel piers below the superstructure facing traffic white or yellow when they are significantly darkened by weathering or other causes so as to be poorly visible against a dark background.

[CGD 84-022, 51 FR 16314, May 2, 1986]§ 118.150Traveller platforms.

The District Commander may require under deck traveller platforms which may significantly reduce the vertical clearance when operated over navigation channels at night to be lighted with quick flashing red lights on each of the four lower corners.

(a) When necessary for reasons of safety of navigation, the District Commander may require or authorize the installation of clearance gauges. Except as specified in §117.47(b) of this chapter for certain drawbridges, clearance gauges must meet the requirements of this section.

(b) Clearance gauges must indicate the vertical distance between “low steel” of the bridge channel span and the level of the water, measured to the bottom of the foot marks, read from top to bottom. Each gauge must be installed on the end of the right channel pier or pier protection structure facing approaching vessels and extend to a reasonable height above high water so as to be meaningful to the viewer. Other or additional locations may be prescribed by the District Commander if particular conditions or circumstances warrant.

(c) Construction. Each gauge must be permanently fixed to the bridge pier or pier protection structure and made of a durable material of sufficient strength to provide resistance to weather, tide, and current. Gauges may be painted directly on the bridge channel pier or pier protection structure if the surface is suitable and has sufficient width to accommodate the foot marks (graduations) and numerals.

(d) Numerals. (1) Each gauge must be marked by black numerals and foot marks on a white background. Paint, if used, must be of good exterior quality, resistant to excessive chalking or bleeding. Manufactured numerals and background material may be used.

(2) The size, type, and spacing of numerals must conform to the Standard Alphabets for Highway Signs and the following table. The nominal day visibility distance is the distance at which the clearance information needs to be ascertained by approaching vessel operators. The District Commander determines this distance for each bridge.

Nominal day visibility distance (feet)Height of numeral (inches)Type of numeralVertical spacing of numerals (feet)Less than 50012Series C2500 to 75018Series C2750 to 1,00024Series D51,000 to 2,00030Series E5More than 2,00036Series E10

(3) The length of the foot marks must be no less than the width of a single numeral used (except numerals 1 and 4), be the same thickness as the width of stroke of the numeral, and extend to the nearest margin of the white background. Foot marks must be spaced every foot for nominal day visibility of less than 500 feet, every two feet for a nominal day visibility of more than 500 feet but less than 1,000 feet, and every five feet for nominal day visibility of more than 1,000 feet.

(4) Intermediate foot marks may be used when more precise determination of actual clearance is necessary. Such intermediate foot marks must have a width of stroke one-half the width of the stroke required for the numeral and shall be three-quarters as long as the primary foot marks.

(5) The horizontal distance between the numeral and nearest edge of the white background shall be no less than one-half the width of a single numeral (excepting numerals 1 and 4).

(6) The minimum width of the white background shall be no less than three times the width of a single numeral (excepting numerals 1 and 4) plus the widths of each additional numeral (when multiple numerals are used plus numeral spacing).

(e) Maintenance. The owner or operator of the bridge shall maintain each gauge in good repair and legible condition. The bridge owner or operator is responsible for the accuracy of the gauge and shall remeasure the vertical distance of the numerals and foot marks below “low steel” of the bridge whenever the gauge is repainted or the structure is repaired.
